Russia's UTAir is to ground its ATR 72-200 fleet at least until the conclusion of the investigation into the fatal departure crash at Tyumen.
The airline says it will use its 15 ATR 72-500s to restore service on the routes operated by the -200s.
UTAir chief Andrei Martirosov insists the carrier has "no doubts" about the operational safety and reliability of the aircraft, but is taking the decision "from a psychological point of view".
He says that the limitation will not affect the airline's network because it will use its ATR 72-500 fleet to make up the capacity shortfall.
The carrier signed for 20 new ATR 72-500s under an agreement sealed a year ago.
UTAir has only two -200s following yesterday's accident. It also uses the smaller ATR 42 for its UTAir Express operation and its Ukrainian regional division.
